BUILDING- CONSTRUCTION.

Application filed September 23, 1925. Serial No. 58,019.

My invention relates to building construction and the like, and is' especially adapted and advantageous for structures such as eX- terior Walls of buildings, and particularly walls of hollow tile, brick, concrete, or concrete blocks, etc., into which nails cannot be driven. The invention is particularly concerned with the application of flexible stucco base, as it is termed, to such Walls. Flexible bituminous stucco base such as described in U.' S. patent to Applegate No. 1,138,069 is a product resembling minera-l surfaced bituminous roofing, and is made by saturating and coating bi-bulous paper or rag felt with bitumen and embedding coarse mineral granules in the bitumen While it is still soft. vVarious advantages that can be realized from my invention'will appear from my description hereinafter of a selected and preferred embodiment.

In the drawings, Fig. I is a fragmentary perspective View of a Wall embodying` my invention, partly in section-and with the eX- terior layers partly broken aiva to illustrate various stages in the construction of such a Wall.

Fig. II illustrates a somewhat different form of construct-ion.

In building axvall of impenetrative character such as described above, I provide for the attachment of stucco base by means of pcnetrable inscts suitably distributed in the wall. Such insets may consist of Wooden strips 5 laid horizontally between courses or unit-s of the hard material forming the wall, at intervals such as six inches or twelve inches (e. g. between successive courses of hollow tile or concrete blocks), and permanently cemented into the structure. Or, if preferred, the insets may consist of courses or units of penetrable character like blocks of cinder concrete 6 laid in alternate courses With impenetrable material at about twelve inch horizontal intervals, for example. As is obvious, the cinder concrete may be laid in a plastic condition so as to bind together the hard units.

The Wall having been built with such penetrable insets, the grittcd stucco base 7 is laid against the Wall and fastened with nails 8 driven through it into the insets. After this, plaster or stucco' 9 may be applied to the base with a troWel, a float, or in any other suitable manner.

Having thus described myclaim -A wall structure comprising a Wall composed of courses of impenetrable hard units with intervening courses of penetrable cin der concrete units laid in plastic condition and serving to bind together adjacent hard units, flexible stucco base secured to the wall by nails passing into the cinder concrete lunits, and a layer .of stucco carried by the ase. t

In testimony whereof, I have hereunto signed my name at Maurer, N. J., this 17th day of Sept., 1925.
